Specification of Letters Patent.

Patented Apr. v2, 191s.

Application filed July 24, 1917. Serial No. 182,469.

To all whom it may concern:

Be it known that 1, MICHAEL E. CUDDY, a citizen of the United States,residing at lVaterville, in the county of Kennebec and State of Maine,have invented new and useful Improvements in F ire-Extinguishers, ofwhich the following is a specification.

This invention relates to fire extinguishers, and comprehends astationary system where by damage resultant from chimney fires may beavoided.

More specifically stated the invention comprehends the provision of aperforated discharge pipe adapted to intersect the smoke passage of thechimney, and which pipe communicates with the supply pipe of the watersystem, or a pipe leading from some other suitable source of supply.

The nature and advantages of the invention will be better understoodwhen the following detail description is read in connection with theaccompanying drawing, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawing forming part of this specification like numerals ofreference indicate similar parts in the several views and wherem:-

Figure l is a vertical sectional view through the chimney showing theinvention applied thereto.

Fig. 2 is a fragmentary enlarged sectional view through theextinguisher.

Referring to the drawing in detail A indicates the chimney, one wall ofwhich is provided with an opening 10 to receive a cast iron cylinder orsleeve 11. The cylinder is of a length equal to the thickness of thewall in which it is embedded, and is closed at one end except for arestricted centrally disposed opening 12. Disposed adjacent the oppositeor open end of the cylinder are internal lugs 13 adapted to be engagedby cooperating lugs 14 projecting from the closure 15 for the open endof the cylinder. The closure cap 15 is provided with a central openingdisposed in axial alinement with the opening 12 in the opposite end ofthe cylinder, and passed through this pair of openings is a pipe 17which projects beyond both ends of the cylinder, one terminal of thepipe intersecting the smoke passage of the chimney or flue A andperforated as at 18 for the purpose to be presently set forth. Thisextremity of the pipe is closed by means of a plug 19 which is threaded:within the open end of the pipe as shown.

The opposite end of the pipe" 17 is-dis posed exteriorly of the chimneyA, and is connected to the offset branch 20 of the T- coupling 21. Oneextremity of the coupling has associated therewith a short length ofpipe 22, which in turn is connected by any well known form of couplingor union 23, with a water supply pipe 24 which communicates with therunning water system of the building. Associated with the pipe 24 at anappropriate point, is a valve 25 which controls the passage of waterthrough the pipe 24 into the nozzle or pipe 17. In order to preventchimney fires, when indications of the same are evident, it is onlynecessary to open the valve 25, when water from the running system ofthe building, will pass through the pipe 241 into the discharge pipe 17and subsequently spread against the walls of the chimney through theperforations 18.

Associated with the opposite end of the coupling 21 is a short length ofpipe 26 which in turn is connected with a water supply pipe 27 throughthe instrumentality of a coupling 28 of any suitable construction. Thepipe 27 leads from a water supply tank 29 which is arranged at anyconvenient location, it being understood that the tank 29 is employedonly when running water is not available. A valve 30 is arranged withinthe pipe 27 at a suitable point in its length, the valve controlling thedischarge of water from the tank 29 and to the nozzle or pipe 17. Itwill be noted that by reason of the construction and arrangement ofparts, that by closing the valves 25 and 30, and uncoupling the unions28 and 28, the nozzle may be removed from the chimney for cleaning.

While it is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent I desire to have itunderstood that I do not limit myself'to the exact construction andarrangement of parts herein shown, and that such changes may beresortedto when desired as fall within the scope of What is claimed.

What is claimed is 1. The combination with a support having an openingtherein, of a sleeve having a length equal to the thickness of saidsupport and wholly disposed within said opening,

2. The combination with a support having an opening therein, of a sleeveWholly, disposed Within said opening, sald sleeve being open at one endexcept for a restrlcted censleeve adjacent its open end; a closure forsaid open end said closure being adapted to engage against one side ofsaid lugs, fingers projecting from said closure and having offsetterminals adapted to engage the-opposite side of said lugs, and saidclosure having a bore disposed in alinement with said aper-- ture.

In testimony whereof I affix my signature.

10 tral aperture, internal lugs formed on said MICHAEL E. CUDDY.
